Hell no, that is never going to happen if traders want to keep playing with their fake bitcoin they can do it but they cannot force everyone else to recognize bitcoin cash as the real bitcoin.
Well, bitcoin cash is never be equal to bitcoin price. If you look at the bitcoin cash price right now, the price is increase highly but yeah it will going down soon. In my opinion, it's really hard to make it happen, the price of bitcoin already so high and there is no altcoin that ever surpass bitcoin price, bitoin cash ? I don't think so.
